freemarker遍历map对象实例,这个与遍历list对象有点不同。当Map里面的key 是Object(String,Integer,etc)等要通过以下的方式来得到。

code

<#list testMap?keys as testKey>
       < option value="${testKey}" >
              ${testMap.get(testKey)}
 
     </option>
</#list>
或者使用:
code
1
2
3
4
5
6
<#list testMap.keySet() as testKey>
       < option value="${testKey}" >
        ${testMap.get(testKey)}
 
     </option>
</#list>
      切记在webwork自带的freemarker中对Map中Key的定义为String类型(如果你想用${Map[key]}这样取值的话;如果用${Map.get(key}这样取值就可以用其他类型,如Map<Long,Object>),更高片本是否可以用其他类型本人未曾验证。

<#list pager.map.get("m") as list>
                        <li<#if (list_index + 1) % 4 == 0> class="end"</#if>>
                            <a href="${base}${list.htmlFilePath}" class="productImage" target="_blank">
                                <img src="${base}${(list.productImageList[0].thumbnailProductImagePath)!systemConfig.defaultThumbnailProductImagePath}" alt="${list.name}" />
                            </a>
                            <div class="productTitle">
                                <#if (list.name?length < 28)>
                                    <a href="${base}${list.htmlFilePath}" alt="${list.name}" target="_blank">${list.name}</a>
                                <#else>
                                    <a href="${base}${list.htmlFilePath}" alt="${list.name}" target="_blank">${list.name[0..25]}...</a>
                                </#if>
                            </div>
                            <div class="productBottom">
                                <div class="productPrice">
                                    <span class="price">${list.price?string(priceCurrencyFormat)}</span>
                                    <span class="marketPrice">${list.marketPrice?string(priceCurrencyFormat)}</span>
                                </div>
                                <div class="productButton">
                                    <input type="button" name="addCartItemButton" class="addCartItemButton addCartItem {id: '${list.id}'}" <#if list.isOutOfStock>value="缺货" disabled<#else>value="购买"</#if> hidefocus="true" />
                                    <input type="button" name="addFavoriteButton" class="addFavoriteButton addFavorite {id: '${list.id}'}" value="收藏" hidefocus="true" />
                                </div>
                            </div>
                        </li>
                    </#list>
